what is this

never seen it before, apparently it comes out of a hole in our live rock, wife said she thought might come out of a white tube thing but wasn't sure.

It's the black thing

 

Darker color may confuse many but that my friend looks like a Eunice see link for simular. BAD NEWS! get rid of it.

 

hi, those pictures look nothing like the pictures of the one in my tank

the black stuff in my tank is moon sand. I'm talking strictly the black worm/slug thing with the 3 antenna on its head.

changed the picture so you better understand what it is i'm asking about

 

Wife said it looked like a centipede so maybe we are on the right track.

It came in my live rock! how in the hell do I get rid of it , we have never seen it before.

 

the rock it was in wasn't important so we just took the rock out , we put it in a bowl of fresh water.

 

the worm never came out, we did however use a sludge hammer and found him

 

And... After smashing the rock. Can you post a picture of the creature?

 

I would say it is a eunicid worm but i cant be sure... The part that made me think it when you mentioned it looked like a centipede... I smashed a rock last night to get mine out of my tank... They are deceiving on how long they are... Good luck with getting it out. Id wait till you see it hide again and immediately take the rock out.

I soaked mine is rodi water for 10 mins hoping it would just evacuate... It didn't so came the hammer and chisel...

 

Looks like a(n) eunicid to me, too. They have five antennae, so you probably just can't see all of them. The big ones are voracious predators, so it's good that you removed it.

Cheers,



Don

 

it broke into 2 parts it was about 5-6 inches long.

It was raining outside so i didn't bother with a picture that is 100% chance though it was an eunicid.

Turns out that my tank looks better with the rock missing anyway.
